Urgent Help required for QT - CINT

Note that you are talking about "Qt-ROOT".
This is an external source code which is (was?) maintained by Valeri Fine.
You can have a look here: sourceforge.net/p/qtroot/wiki/Home/
I believe it used to be ROOT 5 + QT 4 specific and I’m not sure if it works with ROOT 6.
